Renishaw: Linear Incremental Magnetic Encoder System
LM13
The LM13 is a contactless high-speed linear magnetic system
designed for use in harsh environments.
The system consists of a compact readhead and a self-adhesive
magnetic scale.
Simple to install, the LM13 features an integral set-up LED on
the readhead, wide installation tolerances and an applicator tool for the
adhesive-backed magnetic scale. A bidirectional reference is provided that can
be either actuated by a preset mark integrated within the scale or by adding a
reference sticker on top of the scale with the help of a self-aligning
installation tool.
The encoder comes in digital output variants and offers a
range of customer selectable resolutions 1 µm, 2 µm, 4 µm, 5 µm, 10 µm, 20 µm,
25 µm, 50 µm, 125 µm and 250 µm. The LM13 is capable of velocities up to 25
m/s; even at 1 µm it is capable of 4 m/s.
Due to its compact size and internal build, the LM13 is also
suitable for partial arc applications. The self-adhesive magnetic scale can be
installed on surfaces with a minimum radius of 60 mm.
Engineered for extreme service, the solid-state LM13 linear
encoder operates from -10 °C to +80 °C, has water-proof sealing to IP68 and is
highly resistant to shock, vibrations and pressure. The robust magnetic scale
is also resistant to a range of chemicals commonly found in industry. The
non-contact, frictionless design eliminates wear while reducing hysteresis
giving precision at high speeds and accelerations.
The LM13 linear encoder system brings reliable solutions to
tough, hard-working applications including woodworking, stone-cutting, sawing,
metalworking, textiles, packaging, plastics processing, automation and assembly
systems, laser/flame/water-jet cutting, electronic assembly equipment etc.
For applications which demand that the MS scale can be removed
easily please consider TRS track system.
